I've heard that people have gotten good results going to ZBrush using OBJ format, with Output: Quads & Triangles (ZBrush does not handle n-gons well, so you want to switch n-gons off when you export from MoI), and also using the "Divide larger than" setting to dice polygons up into smaller more evenly sized pieces also helps a lot, there is an illustration of that here: http://moi3d.com/forum/index.php?webtag=MOI&msg=1549.4
It's free for now and the res is high, OK frame rate, and it's full screen (no audio). I've used it, it's great. Techsmith (Camtasia) is doing a test martket I guess. I haven't heard of a size limit, and Techsmith tells me the free offer will last for some time still.
There is also Slideshare which is really good for making slide show tutorials. I saw one for an open-source box modeling program and I found stuff really sinks in fast with this simple type of Powerpoint type of presentation, maybe better than a video because you control the progress step by step.
